Question 2 (Multiple Answer)

To determine the vision for depth perception, we analyze each option:

• Tri vision: Not a recognized term for depth perception.
• Focal vision: Focused central vision, not for depth.
• Peripheral vision: Helps with detecting motion and context, not depth.
• Paracentral vision: Also not the primary for depth. Wait, correction: Actually, for depth perception, the relevant visions here—wait, maybe a misrecall. Wait, no, the correct ones for depth (stereoscopic or related) but among the options, maybe a typo or context. Wait, maybe the intended correct is focal? No, wait, depth perception uses binocular vision (but not an option). Wait, maybe the options have errors, but re - evaluating: In some driving/vision contexts, focal vision (central, detailed) and paracentral? No, maybe the correct answers are focal vision and paracentral? Wait, no, let's think again. Depth perception (judging distance) is related to how we focus and use central and near - central vision. Wait, the options: "focal vison" (maybe typo for focal vision) and "paracentral vision" might be correct? Or maybe "focal vision" and "peripheral"? No, peripheral is for side motion. Wait, perhaps the correct answers are focal vision and paracentral vision? Or maybe the question has a different context. Alternatively, maybe the correct options are focal vision and paracentral vision. But I think the intended correct answers are focal vision and paracentral vision (assuming the typo in "focal vison" is a spelling error).

• Option 1: "what you can see while down the road at a specific target" is focal vision (focused on a target), not field of vision.
• Option 2: The field of vision (in front) is approximately 180 degrees in front of a person.
• Option 3: Peripheral vision is part of the field of vision, not the definition of field of vision.
• Option 4: Paracentral vision is a part of the visual field, not the definition of field of vision.

• Focal vision: For focused, central tasks (like looking at a specific object).
• Paracentral vision: Near - central, not for side motion.
• Peripheral vision: Detects motion and objects in the side (peripheral) areas.
• Double vision: A visual disorder, not for detecting side motion.

Answer:

B. focal vison, D. paracentral vision
